The Clutch Masters FX400 clutch kit utilizes the Power Plus I Pressure Plate to make sure there is plenty of pressure being applied to the clutch disc, forcing the transmission to power the wheels quickly and effectively. The FX400 is designed for vehicles with more aggressive power modifications where outstanding holding capacity and rapid heat dissipation are critical. Multiple pads create a quicker engagement of the clutch disc to the flywheel and pressure plate allowing very quick power transfer to the transmission and therefore, to the wheels. Multi-pad discs can sometimes cause chatter and harshness when starting off from a stop so choose this clutch carefully for your application. All components that complete a clutch kit are included. FX400 kits feature ceramic clutch disc material that is typically not expected in increase life expectancy over stock but rather, increase holding capacity and durability under stress and high performance situations. Clutch life is dependent on many things including power levels, driving habits, break-in procedure, and flywheel pairing. The FX400 requires a minimum of 500 break-in miles before heavier use.
